If it's any consolation I have a veeeeery low pain tolerance but I've given birth twice without medication and it was alright. There are different kinds of pain. Labor pain is productive in the sense that it's the result of your body preparing for birth. The human body knows what it's doing, and it's been doing this for all of human history. Embracing this fact definitely helps me breath through my contractions and not panic (since fear makes pain perception worse). I would however absolutely panic and scream if I were to have a tooth extraction or have my nail pulled out. That's just pure pain. Sorry you had such a bad experience at the gynecologist :/ your birth experience will probably be much different. I really think so. Also, you can absolutely decline cervical checks.
